ADJUSTABLE FIXTURE S'IUD AND SUPPORT.

Specification of Letters Patent. Patented Apr. 13,1915.

Application filed October 1, 1914. Serial N 0. 864,479.

To all whom it may concern.

Be it known that I, ALEXANDER M. KNAU- BER. a citizen of the United States, residing at Oak Park, county of Cook, State of Illinois. have invented a certain new and useful Improvement in Adjustable Fixture Stud and Support, and declare the following to' be a full,.clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same. reference being had to the accompanying drawings, whichform a part of this specification.

The principal object of my invention is to produce a simple and novel device for adjustably attaching wall plates for pipes or conduits. connection boxes, switch boxes and, in fact, all the usual wall or ceiling attachments required in modern building constructions to cleats or other supports, whereby the attachment may be easily and conveniently made and will be very secure.

A further object of my invention is to produce a simple and novel device which may be used not only for securing a wall or ceiling attachment in place but, if the latter be secured in place by other means, will serve as a stud for supporting a fixture.

A further object of my invention is to produce a simple and novel cleat which will permit a wall or ceiling attachment to be rigidly supported at any point between two beams by a cleat of comparatively light weight.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but, for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein:

Figure 1 is a section through two wall or ceiling joists or beams having secured thereto my improved cleat and an attachment secured thereto by means of my improved fixture stud; Fig. 2 is a View of the cleat shown in Fig. .1 in.a plane at right angles to the plane of Fig. 1; Fig... 3 is a section on a larger scale taken longitudinally through the cleat and the ceiling or wall fixture atthe center of the latter; Fig. 4: is a-section' on line Fig. 5 is a view similar to Fig. 4 with the cleat omitted.

Referring to the drawing, 1 represents any usual or suitable wall or ceiling attachment having an axial opening, 2, and 3 is a construction cleat on which the attachment is adapted to be supported;

In accordance with my invention, I take a short section of pipe, 4, of. a diameter which will permit it to be inserted through the opening 2 in the fixture, screw thread the pipe on its exterior and cut therefrom at one or more points suitable ears, 5, which are bent laterally. In the preferred form, each ear is formed by cutting two parallel. longitudinal slots inwardly from one. end of the pipe section and then bending laterally a piece lying'between the two slits. ears are preferably not bent quite at right angles to the pipe section but are left at an angle to this axis. The parts are so proportioned that the slot formed in the end of the pipe section by bending two ears laterally is just wide enough to receive the The cleat 3; the length of the slotted portion 7 being suflicient to permit it to project through the upper or rear side of the atbe seen that when the parts are assembled in the manner just described, and the locking nut is tightened, the cleat is pressed against the upper or rear side of the attachment and the. latter is pressed against the ears 5. In other words, the attachment and the cleat are clamped-together between the ears on thepipe section and the nut.

It will be seen that with my improved" stud, the cleat may'be fastened in position before the attachment or the stud is placed on it; the stud being slipped'through the attachment and over the prepared cleat, the

nut being applied, and the attachment being I then slipped along the cleat to bring it to I the desired position before the nut is finally tightened. By inclining the ears, as shown,

they act as. stiff springs which yield under the pressure of the nut when the latter is tightened and thus serve as nutqlocks to prevent the accidental loosening of the nut.

should be made'as light as possible. I of the difficulties encountered with. light 'ing operations. The spring action of the ears serves to lock the stud tightly and prevents it from becoming loose under the con' ditions just described. t I,

For the. sake of economy and convenience' in handling, metal construction cleats One I cleats is thatthey do not support the attachment rigidily yieldable. V

enough, being more or. less In accordance with one feature of my invention I have produced a simple construction. cleat which may be-made quite light 1 and yet be, comparatively rigid. Thus, as

indicated Figs. 1 and 2, I make the cleat in the formof a small flat bar of steel having a main straight portion, 3, an inclined portion, 7 and an ear, 8;.the ear 8 being at right angles to the member 3 and the inclined portion 7- making a considerable angle with the member 3. ,Insecuring the cleat in p1ace,the ear 8.is placed-against the side ofoneoftwo adjacent joists or beams, 9; and 1Q,fwhil thev main portion, 3, is laid against the outer'edge ofthe other beam. Theftwo faces with which the two ends of aicleat' engage are atrightangles to each otherand therefore a good bearingwil-l be obtained atneachend ofthe cleat. It will'be seen that acleat of this ,kind. is notj limited in its, :useQto beams having a single definite spacing, butmaybeapplied regardless of i the: spacing between the beams, providedthe cles it s h r- Sa r a he, i id y a t le i v i q n r ed,k th nc i ed portion, 7 servesas a rigidlbrace orabutment sothat eat: s l ngi ou h. t spa thee-beam heaw e he ma n p r an m y r -la h beam ,with which it. engagesdf the beams are,
